To all wia-0m t `may @ongerief Be it known that'l, HAnnnRrAUeUsrrrNEJENKINS, subjeet of theKing ofn Great Britain, `residing,` at 34C UnionStreet, lI-Iavjvel'a, Deininion et' New Zealand, ,have invented a newand useful JointingrMeans, 'otwheh the following is a specifieation.

This invention has `leeen devised with the object of providing meansWhereby-astrong joint maybe efeeted between twoy members of any artiolejofstructure that the assembly thereof have e to lhe conneetedtogetherin a inanner sueh that the Connection may hema-deer broken atwill, `Without the employment "of skilled labour.

"filhe rail nieinheiyof, the joint is provided Witha .tongue E'of metalthatis fastenedjby riveting, "or in `any other vapprevled manner, to theinside` surface Ofjtheertiealiportion (if the rail so thatit 'projectsoiitiyards and ng atabtle tep tothe ander#` leo in horizontal line suolithat when the rail is placed end on against the post member of thejoint, the tongue will pass into the slot D thereof. The tongue is madeof such a length as to project beyondthe outer surface of the block Dwhen they are assembled together and in its projecting portion it isformed with a slot E extending longitudinally along it. The slot is madeof two widths as shown in Figures 2 and 5 and is so positioned that theinner portion of its width extends in the line of the shoulders D2 ofthe block D while the outer portion extends outside the line of suchshoulders.

A wedge F is provided to pass down through the slot E. This wedge ismade of equal thickness to one portion of the slot so that it may beplaced to extend between the shoulders D2 and the other end of the slotand thus when forced down to lock the two parts of the joint together,or it may be drawn upward and freed from the jamb and then placed in theouter portion of the slot so that the shoulders will be free of thewedge and the two parts may be drawn apart. This wedge is retainedpermanently within the slot E by forming it with a slot f runningthrough most of its height and through which a pin E2 that is driventransversely in through the tongue E and across the slot E, also passes.

Thus the parts may be assembled together by drawing the wedge F up tothe limit al lowed by its slot f, placing it in the outer portion of theslot E so that it will pass freely over the shoulders D2 as the tongue Eis passed into the slot D', and then positioning the wedge in the innerportion of the slot and forcing it downward to wedge between theshoulders and the end of the tongue slot. This draws the joint membersfirmly together and holds them in rigid engagement.

In the form of joint for use with wooden side rails shown in Figures 8and 9 the same general features of construction are adapted, but in thiscase the block on the post member C is replaced by a socket D thatreceives the end of the rail B and makes a close lit all around it. Theoutside of this socket is formed with the slot D formed to extend acrossits middle and the shoulders D2 are formed on both edges of such slot onthe outer surface of the socket. The tongue E is in this case xed on abase plate G that is adapted to be countersunk into the surface of theside rail and to be fastened thereto by screws. It is also formed withthe same form of a slot E and is provided with the same type of wedge Fas in the previous example and these work together in shown in Figures 8and 9 although designed for a similar purpose, viz, for use with woodenside rails. In this case the saine socket Dis employed for the postmember and it is made with the slot D and with shoulders D2 on each edgeof the slot. This form of joint however provides for the tongue E beingreplaced by a coach bolt H that is screwed transversely into the rail Band the head of which is adapted to be engaged by the locking wedgeF.The locking wedge is adapted to be driven down bctween the shoulders D2and the stem of the bolt H, behind its head, and thus to lock the railwithin the socket. its upper end is guided on its edge opposite theshoulders so as thus to keep fiat, by-

means of the undercut knob J formed on the outside surface of the socketD and properly positioned to act in the manner mentioned. lf desired,the wedge may be made a permanent attachment to the socket piece byforming it with a slot f extending longitudinally through the lowerportion of its length, and by fastening it thereto by *"1 means of thestaple J passed through such slot and fixed in the face of the socket.This slot allows foi the wedge being lifted far enough to cause itsnarrow lowerend to be turned out from behind the shoulders and bolt headand then swung round on the staple out of the way of the side rail beingdrawn from the socket.

The form of joint shown in Figures 8 and 9 is adaptable for use inattaching the rails of a table frame to the table legs and suchadaptation is illustrated in Figures 12 to 14 in which Figure 12 is anend View of the socket member for aitixing to the table leg, Figure 13isa cross section of the rail showing the tongue member aixed thereto, andFigure 14 is an inside elevation of the socket member. The constructionand working of these parts follows closely in design those of thecorresponding parts in Figures 8 and 9 but in yorder to provide forextra rigidity, the inside of the socket is preferably made as fins K,extending forwardly from the to a and bottom, and these pass intogrooves l (Figure 13) made in the end of the rail to receive them, asthe rail is passed into position within the socket.

'For securing a table top to the underframing the jointing means may bemade in the manner shown in Figures 6 and 7 These means comprise thecombination with the tongue E affixed to the inside face of the frame Band having the slot E and wedge F made and fitted in the manner beforedescribed, of a light bracket N of right angle form, one member of whichis screwed to the underside of the table top O1 so that the other memberis adapted to pass down against the inside face of the frame B. Thisvertical member is slotted to pass over the The wedge at lOOBwdraiingmand in the manner already .fully explained. wk
